Barcodes type

GS1 barcodes

Barcodes are symbols that can be scanned electronically using laser or camera-based systems.

They are used to encode information such as product numbers, serial numbers and batch numbers. Barcodes play a key role in supply chains, enabling parties like retailers, manufacturers, transport providers and hospitals to automatically identify and track products as they move through the supply chain.

GS1 manages several types of barcodes. Each is designed for use in a different situation.

EAN/UPC barcodes

Instantly-recognisable, EAN/UPC barcodes are printed on virtually every consumer product in the world. They are the longest-established and most widely-used of all GS1 barcodes.

The EAN/UPC barcode family has transformed the world of retail. See how it works >

One-dimensional (1D) barcodes used exclusively in general distribution and logistics

GS1-128 and ITF-14 are highly versatile 1D barcodes that enable items to be tracked through global supply chains. The GS1-128 barcode can carry any of the GS1 ID keys, plus information like serial numbers, expiration dates and more. The ITF-14 barcode can only hold the Global Trade Item Number (GTIN) and is suitable for printing on corrugated materials. See how it works >
